Noctua NA-FC1, 4-Pin PWM Fan Controller (Black)

Product Information

Accessing the control knob is impossible without opening the chassis, limiting the manual operation somewhat.

While most fan controllers are voltage based, the NA-FC1 uses the more sophisticated Pulse Width Modulation (PWM) technique that allows for more efficient control and lower minimum speeds, regardless of the fan’s starting voltage. That tiny power source could be a microcontroller GPIO pin such as an Arduino I/O pin, a 555 timer’s output pin, among others. A good fan controller can really help your gaming experience by taking heat stress off your CPU and letting it run more efficiently. If you own RGB fans, LED strips, or other RGB accessories made by NZXT you should definitely check out this fan controller. Once installed, you can control your cooling and lighting effects in your PC using NZXT CAM software.Registered office: Klarna UK Limited, 7th Floor, 33 Cavendish Square, London, W1G 0PW, United Kingdom. Fan controllers can be used to manually adjust fan speeds, change your RGB lighting, or for software control of multiple fans through a single header. The PSU is fine (and has survived at least three further short circuits), however, my experience tells me that even a good PSU like mine which has commendable SCP (short circuit protection) doesn’t guarantee the well-being of your components. It’s not a big deal, and although it may involve a fair bit of work, don’t worry about it – I had to debug my circuit (and in some ways, I am still debugging it), and I had the overclockers.

This is the release repository for Fan Control, a focused and highly customizable fan controlling software for Windows. In other words, all fans will be controlled according to the data from the unit connected to the Fan 1 header. The trick it has which makes it useful to have if you use other Razer products is that it can be configured through Razer Synapse. It monitors the temperature of an external NTC thermistor and generates a PWM signal that can be used to control the speed of a 2-, 3-, or 4-wire fan. The layout that I chose (above) is almost identical to the schematic of the circuit, which helped a great deal when the time came to put the circuit together and make sure all connections were made in the right place.You can also set a temperature alarm too, activating when the temperature exceeds or drops below the set temperature.
